Valterra

<h3>About Valterra Products</h3><p><strong>Valterra Products, LLC</strong> has been a cornerstone of the recreational vehicle supply industry since 1981. Founded by the Grengs family in Southern California and headquartered in Mission Hills, CA, the company grew out of an earlier plastic injection molding business that produced RV gate valves, toilets, and plumbing fittings. Over four decades later, Valterra has evolved into one of the premier RV suppliers in North America, serving both OEM manufacturers and the aftermarket.</p><p>What sets Valterra apart is its rare combination of family-owned roots and broad industrial reach. Many employees have worked at the company for 20, 30, or even 40-plus years — a testament to a culture that values craftsmanship and continuity. That same long-view approach shapes how Valterra develops products: thoughtfully, durably, and with the real-world needs of RV owners in mind.</p><h3>A Family of Brands Built for RV Life</h3><p>Through strategic acquisitions, Valterra has assembled a powerful portfolio of complementary brands. The company added Mighty Cord for power connections, Phoenix Faucets for plumbing, Odorlos for eco-friendly tank treatments, Diamond LED for lighting, GoPower! for solar systems, and Minder Industries — the maker of the widely recognized <strong>TireMinder</strong> line — for tire pressure monitoring. This family of brands allows Valterra to address nearly every system aboard a modern RV.</p><p>Sanitation and waste management have always been among Valterra&apos;s most critical product areas. Their <a href="/7632-valterra-rv-sewer-hose-18294">RV sewer hoses</a> are renowned in the industry, featuring purpose-built lines like the Dominator, Silverback, and Viper series — each engineered for different usage demands, from compact compartment hoses to heavy-duty full-system kits. Whether you need a simple extension or a complete dual-drain setup, Valterra&apos;s sewer solutions cover the spectrum.</p><p>On the safety side, Valterra&apos;s <a href="/7632-valterra-tire-pressure-monitoring-system-kit-55374">tire pressure monitoring system kits</a> — marketed under the TireMinder name — give RV drivers real-time visibility into tire conditions. These systems are purpose-designed for the multi-tire complexity of motorhomes, fifth wheels, and tow vehicles, with options that support monitoring up to 20 tires simultaneously via dedicated displays or smartphone apps.</p><h3>Serving Multiple Industries</h3><p>While the RV market is Valterra&apos;s flagship, the company&apos;s product lines extend into the Pool &amp; Spa, Plumbing, and Bus &amp; Motorcoach industries as well. Their contract manufacturing division further serves client companies looking for custom-manufactured components at scale. This diversification reflects a company that has grown deliberately and sustainably, without losing focus on quality and customer service.</p><p>For RV enthusiasts, weekend campers, and full-time travelers alike, Valterra remains a go-to source for reliable, well-engineered products that make life on the road cleaner, safer, and more comfortable.</p>
